Hello, yes they finally reply, but sadly its not a good news. First, they told me that they have sent the notification to the wrong email address. Kinda makes me question how they made such mistake when they once emailed me so I can submit additional documents

Then they mention that the notification email was to inform me that I did not qualify to the program (I know very sad I waited for nothing

)
At the moment I'm preparing my application as a privately-finance student to the same program instead. My plan is to get a Japanese private scholarship as a replacement. And just apply for tuition fee exemption everytime. For those who really want to join the program but didn't get MEXT this is an option if you do not want to wait another year.
For those whose still waiting for reply, I believe you should get a the final notification around June-July. Goodluck everyone!!!

and be safe especially this time.
